This dynamic frequency allocation ensures high robustness of the system even if the frequency occupation changes during the meeting. All these carriers may be used Allowed RLAN high band carriers in USA and Canada (FCC regulations) ; these carriers may not be used. Allowed RLAN high band carriers in Japan; these carriers may not be used. In the “5 GHz ISM” frequency band, there are 4 nonoverlapping carriers. All of these carriers can be used. Televic Conference Systems 5.3. Frequency Planning When the Confidea wireless system is set to manually select the wireless carrier frequency, then you must make sure the Confidea wireless carrier does not overlap the already occupied WiFi wireless carrier channels. 2013-06-28 20 Note : Note : Wifi access points and use of 5gHz band Selecting frequency When using manual frequency selection in 5gHz band , ideally the frequency selection is done in such way that between 2 used frequencies , there is a 40Mhz “distance” to avoid interference by RF sidebands. Some wifi accesspoints which support IEEE 802.11n may also use 5gHz band when they are configured in DualBand or Backhaul mode! 5.3.2. Use of multiple Confidea wireless systems When the Confidea wireless system is set to automatically select the carrier frequency, the Confidea carrier frequency will be dynamically set to another channel if another Confidea wireless system occupies the same channel. This dynamic frequency allocation ensures that each Confidea wireless system will be set automatically to different frequencies. When the Confidea wireless system is set to manually select the wireless carrier frequency, you must make sure the Confidea wireless carriers of the different rooms do not overlap each other. 5.4. Max range of WCAP A single WCAP has a range of 30m in “open field” . However the max range can be significantly less depending on the positioning of the WCAP itself and direction of the antennas in relation to the position of the delegate units. See chapter 5.5 for detailed info Attention: Certain buildingmaterials like concrete , or metal may absorb part of the RF signalradiation, resulting in a reduction of the max distance between the access point and units. Note : Manual or automatic frequency selection? If more than one WCAP or Wifi accesspoints are in the same room or within 30m. range , it is strongly advised that not more than one of them uses automatic frequency selection , to avoid that the frequencyscanning is disturbed by the other accesspoint(s) . If multiple accesspoints are used within each other’s reach, manual frequency selection based on frequency planning is strongly recommended . Televic Conference Systems 2013-06-28 21 5.5. Guidelines on optimal WCAP positioning and direction of antennas Note : When the antennas of the WCAP are positioned very close to a wall or ceiling , this may result in absorption of the RF signal , which can decrease RF signal quality. Attention: Do not place the WCAP behind obstacles like walls , cabinets, panels, projection screen, glass screens etc… , as they significantly reduce RF signal strength and quality 5.5.2. Optimizing the position the antennas Note : 5.5.1. Positioning the Confidea Wireless Access Point It is important not to point the antennas directly to the units Below you can find how to select a correct positioning of the WCAP. Figure 5.3 WCAP position antennas Figure 5.1 WCAP position hight for detailed view see of optimal antenna positioning see Figure 5.4 WCAP position antennas Note : Choosing the correct angle of the antennas in relation to the position of the delegate units is beneficial to a good overall RF link quality between WCAP and delegate units Figure 5.2 WCAP position to wall Televic Conference Systems 2013-06-28 22 Figure 5.4 WCAP position antennas Televic Conference Systems 2013-06-28 23 5.6. STM/ATM mode Since Confidea wireless conference system 1.1 and following there is new feature which enables a choice between 2 transmission modes :. 5.6.1. STM mode This is the same standard transmission mode as is used in the Confidea wireless conference system 1.0 5.6.2. ATM mode This mode is specifically intended to be used in very challenging environments where a high density of wifi signals is present (due to wifi access points as well as so called smart devices ), which may cause RF interferences when STM mode is used. ATM is the preferred setting if no more then 4 interpreter channels are needed (See also chapter 12.3.1) Note: In environments were interference from wifi signals Is an issue , ATM mode in combination with a manual fixed frequency setting in the RLAN LOW or ISM 5gHz band is recommended to limit the risk of disturbed audio due to RF interference !

(see also Note 11.2-1 Televic Conference Systems 2013-06-28 59 Caution: Do not switch off the Confidea Wireless Access Point or any of the Confidea wireless Delegate Units while the upload is in progress. Note: 11.4.3. What webbrowser to use? If the connection is lost after a failed update session then the hard coded web server link has to be used to proceed with the update. Since there exists a wide variaty of web browsers , which are subject to regular updates , 100% correct functionality of Confidea wireless webserver on all browser types can not be guaranteed, because some actions may be blocked by specific browsers. http://192.168.0.10/sublinks/update_main_ gold.shtml If the current Firmware version is 0.21 or lower , only Internet Explorer should be used for updates 11.4.2. New update method If the current Firmware version is 2.xx.xx or higher then Google Chrome , Firefox or Safari is The update procedure has been significantly simplified compaired with Confidea 1.0. Only one file for WCAP+ and one file for WDU need to be uploaded. The updates are done via “tuf” files which contain all necessary files, that the device needs recommended. When using Internet Explorer progress bars may not be visible depending on I.E. version. Remark if I.E. was used and progressbars are not However , to make older equipment compatible with this new update method , some additional steps may be required , as will be explained further in this procedure Before continuing the update procedure , initialize the delegate units and check via the “unit monitoring “ tabblad which ones have a firmware version < visible , it is still possible to open another connection with the WCAP+ using i.e. Google Chrome and this way monitor the update progress. 11.4.4. Updating WCAP+ with older firmware 03.04.XXXX (WCAP+ firmware version lower then 2.01.09 ) This info will be needed before starting the WDU update later on in this procedure Televic Conference Systems 2013-06-28 60 A green progress bar appears at the bottom of the screen and after +/- 5 sec the screen is refreshed. Upload is finished. Note: Depending on the used webbrowsertype and version , the progressbar may not always be visible. For WCAP+’s with AP SW version 2.01.09 or higher , steps 1 , 2 and 3 must be skipped First the new webserver needs to be loaded into the WCAP+ ; for this select the Service – Update screen Attention : The name of the file must be exactly “ firmware_ap.bin ” Step 2: In the Web Server Update screen , browse to and select the “webrombin.bin” file to update the webserver. Figure21: Update screen Select “upload to AP”. A green progress bar appears at the bottom of the screen and after +/- 5 sec the screen is refreshed. Upload is finished.

SW update must be done in the following order: Step 1: In the AP Update screen , browse to and select from the” transitional files for WCAP plus” , the DSP Bootfile “firmware_ap.bin” file to update the AP. Select “upload to AP”. Televic Conference Systems Restart the WCAP+ After reboot of the WCAP+ the update screen should look like shown below 2013-06-28 61 Step 3: Note: After updating the WCAP+ , check through the webserver “summary” section if the SW update has been successfull, as some types of anti-virus SW and/or firewall restrictions may block the updates . If needed disable the anti-virus SW for the duration of the WCAP+ SW update. firmware version of transitional files should be 2.01.11 Remark : if the webpage is not automatically reloaded after 5 min. , you may reload the page manually After upload is finished the WCAP+ reboots automatically and login is needed . Crosscheck the firmware , FPGA and Webserver version with the ones mentioned in the readme.txt file (see chapter 11.4.1) , to check if update has succeeded 11.4.5. Updating WCAP+ with firmware version ≥ 2.01.09 Update procedure has been significantly simplified compaired with Confidea 1.0. Only one file for WCAP+ needs to be uploaded. Every “tuf” file contains all DSP , FPGA and template files , that the device needs Step 4: In the AP update screen , browse to and select the “wcap-…. tuf” file to update the WCAP+. Click on “upload “ to start the upload procedure : following screens appear Televic Conference Systems 2013-06-28 62 Step 5: Caution: Before starting SW update of WDU, make sure the batteries of ALL WDU’s are charged up to at least 20% ! During WDU SW update procedure do not move any WDU’s ! Updating SW of WDU’s with insufficient batterycharge or while WDU’s are moved around may result in slowdown of or even failed update procedure ! 11.4.6. Updating WDUs with firmware < 03.04.xxx Make sure the STM mode is selected in the“Conference management – general “ tabblad In the “Init units” tabblad , select “manual init” > “clear list” > “start init” to intialise all WDUs with a firmware version < 03.04.XXXX > “Save and stop init” First check if all units are still connected via the “Conference Management -> Unit Monitoring” tab. Step 6: Caution: Before starting the WDU update , make sure to select a manual black marked RF Frequency setting , NO RADAR frequency (radar frequencies are marked in blue in RF freq drop down list)! Automatic frequency setting or radar frequency setting can cause a failed update due to sudden frequency jump. In the AP update screen , browse to and select the “transitional-wdu-1.2.xx.tuf …. tuf” file to update the WDU. Click on “upload “ to start the upload procedure : following screens appear . If the progress bar does not appear immedialtely , it is allowed to do a refresh of the update screen to check if the upload has indeed started. This update process may take up to +/_ 5min. After the update , the WDUs will reboot automatically . For WDU’s with firmware version 3.0.4 or higher , step 5 and step 6 must be skipped Televic Conference Systems 2013-06-28 63 During the update the leds next to the microphone button should blink red for a few seconds and shortly green , red for a few seconds again , etc… If the leds blink only red , then the update procedure is not continuoing because one or more delegate units are not responding , e.g. because of an empty battery Check “Unit Monitoring tabblad” and verify if all units have reconnected with the new SW version Crosscheck with the content of the readme.txt file (see chapter 11.4.1) In the “Init units” tabblad , select “manual init” > “clear list” > “start init” to intialise all WDUs with a firmware version ≥ 03.04.XXXX > “Save and stop init” First check if all units are still connected via the “Conference Management -> Unit Monitoring” tab. Step 8 In the AP update screen , browse to and select the “wdu-1.2.xx.tuf …. tuf” file to update the WDU. Click on “upload “ to start the upload procedure : following screens appear . If the progress bar does not appear immediately , it is allowed to do a refresh of the update screen to check if the upload has indeed started. If some WDUs show alternating green leds , then this means that the update failed due to interference or bad RF link . In this case repeat the steps 5 & 6 until all units are updated to firmware version 03.04.XXXX and startup normally 11.4.7. Updating WDUs with firmware ≥ 03.04.xxx Update procedure has been significantly simplified compaired with Confidea 1.0. Only one file for WDU’s needs to be uploaded. Every “tuf” file contains all DSP , FPGA and template files , that the devices need Step 7 Make sure the STM mode is selected in the “Conference management – general “ tabblad Televic Conference Systems 2013-06-28 64 During the update the leds next to the microphone button should blink red for a few seconds and shortly green , red for a few seconds again , etc… If the leds blink only red , then the update procedure is not continuoing because one or more delegate units are not responding , e.g. because of an empty battery The entire update process may take up to +/_ 30min. After the update , the WDUs will reboot automatically . Check “Unit Monitoring tabblad” and verify if all units have reconnected with the new SW version Crosscheck with the content of the readme.txt file (see chapter 11.4.1) If some WDUs show alternating green leds , then this means that the update failed due to interference or bad RF link . In this case repeat the step 8 until all units are updated to firmware version 03.04.XXXX and startup normally . Televic Conference Systems 12.1. Setup 12.1.1.

Country selection Note: Select the correct country the system is working in. This setting will affect the available frequencies and output power of the HF-carriers. Use this information when you contact the service department in case you experience problems with the system. 12.1.2. TCP/IP settings 12.1.4. Admin Identification The default password = 123 System Name: Defines the user-defined system name. Change password Base MAC Address: Displays the MAC addresses assigned to the system. IP configuration Only users that know the password are authenticated to use and consult the Confidea WCAP web pages! In this section the password can be redefined: In this section you can configure how the system will acquire its IP address 1. Enter the OLD password 2. Enter a new password (Max. 30 characters long) 3. Confirm the new password 4. Submit the values to the server and wait for the result. 5. When no password is entered , the webserver has an auto login function IP Address Mode: Retrieves the IP address using DHCP or Static. DHCP: Retrieves the IP address using DHCP. Static: The IP address is statically defined. IP Address: Defines the system IP address. Subnet Mask: Defines the system IP address mask. Televic Conference Systems 2013-06-28 66 Automatically Note: The old password will work as long as no positive feedback has been received. When the ‘Automatically’ setting has been selected, the system will decide automatically on which frequency to operate, based on its measurements of the available spectrum. In this way, interference with equipment that operates nearby is avoided. 12.1.5. License Frequencies listed in BLACK color. When one of the frequencies is selected out of the list, the system will be forced to work on that frequency and will not automatically switch to another channel in the case that interference should occur. The default license allows up to 16 translation channels to be distributed to the delegate units when the Confidea wireless system is used in combination with a TCS5500 , TCS2500 or Confidea wired Wired system. Each license code is linked to the serial number of the WCAP+. Frequencies listed in BLUE color. Some frequencies require a special procedure before equipment can occupy the channel. These frequencies are indicated with a blue color. Compliancy with the ETSI EN301893 standard requires a channel availability check on these special frequencies before one of these frequencies can be used. There are currently no extra license depending features available This also implicates that, although an operating frequency has been manually selected, the system will still switch to another available channel when a radar signal or other interfering signal has been detected on that channel. 12.2. RF Configuration 12.2.1. General Power Room size: the transmitted output power will be adjusted to cover the configured room size. Note: The channel availability check takes 60 seconds. During that time delegate units cannot connect to the Confidea Access Point The system will select the appropriate power setting when the auto setting has been selected Frequency The drop down list box allows you to select the frequency on which the system needs to operate. Televic Conference Systems Frequencies listed in light BLUE color. 2013-06-28 67 A channel where radar detection is necessary and the availability check has been performed.

Some frequencies will be marked in red indicating that an interfering signal was detected on that channel. The interference severity can be monitored in the quality pages. Frequencies listed in dark RED color. In a channel where radar detection is necessary, an existing signal has been detected. 12.2.5. Quality 5.8 GHz ISM On this webpage the expected quality for each possible RF channel in the 5.8 GHz ISM band can be monitored. This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. 12.2.2. Quality 2.4 GHz ISM Channel Quality Note: On this webpage the expected quality for each possible RF channel in the 2.4GHz ISM band can be monitored. The channel availability is visualized using colors: This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. See also notes on Page 54 A full GREEN bar indicates the channel is available 100% of the time. This channel is thus safe to use. A full RED bar indicates the channel is fully occupied by other radio devices. This channel should not be used to operate the wireless Confidea system. The more activity on a channel, the more the corresponding bar will color RED, and thus the more likely interference will occur with other systems. 12.2.3. Quality 5.15 – 5.35 GHz On this webpage the expected quality for each possible RF channel in the 5.15-5.35 GHz band can be monitored. This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. 12.2.4. Quality 5.47 – 5.725 GHz On this webpage the expected quality for each possible RF channel in the 5.47-5.725 GHz band can be monitored. Televic Conference Systems 2013-06-28 68 Defines the maximum number of chairmen microphones that can be activated on top of the already active microphones , even if the maximum number of active microphones is already reached. The system can handle a total number of max. 6 active microphones , including chairman microphones. Note: From time to time, the Confidea wireless system will also measure its own activity in the channel on which it is currently operating. This results in a RED indication on the corresponding bar graph, but does not affect the reliable operation of the system. Remark: Max 1 chairman can be used in stand-alone mode. The Confidea CS software or Confidea central unit can be used if more than 1 chairman units are required. 12.3. Conference Management Note: 12.3.1. General Choosing a high number of active microphones will limit the number of interpretation channels. Conference Configuration Maximum Number of Active Microphones: Defines the maximum number of simultaneous active microphones. The system can handle a maximum number of 6 active microphones. Microphone Mode: Defines the conference mode. No request : Microphones can only be switched on by operators via users SW With Request: Enables the participant to send a request to speak to the chairman or conference operator by pressing the microphone button (or to cancel his request by pressing the microphone button again). Once the floor is requested, the green LED on the right side of the microphone button Maximum Number of Guaranteed Chairman Microphones: Televic Conference Systems 2013-06-28 69 will flash. This means that the conference unit is in request mode. The chairman or conference operator grants the participant the permission to speak by using the NEXT button or by clicking the green microphone on the computer screen in case the Confidea wireless system is connected to a central unit and PC control software is used. While the conference unit is in request, the indicator ring of the microphone will flash. With Request No Clear: Enables the participant to send a request to speak to the conference operator or chairman. However, he cannot cancel his request. The chairman or conference operator grants the participant the right to speak by using the NEXT button or by clicking the green microphone on the computer screen in case the Confidea wireless system is connected to a central unit and PC control software is used. While the conference unit is in request, the red signal ring of the microphone will flash. When the maximum allowed number of microphones are switched on, activation of an additional microphone will automatically switch off the microphone that was active for the longest time. Again, the Chairmen units can always be activated, regardless of the number of microphones already switched on. Group 1: Enables one microphone at a time to be active without a request for activation. Other participants can switch their microphone in request mode; the first applicant gets the floor when the delegate who has the floor turns off his active microphone or when the chairman or conference operator grants the participant the permission to talk by using the NEXT button or by clicking the green microphone on the computer screen. Group 2: Direct Access: Enables the participant to turn on or off his microphone at any time. The only limitation here is the maximum number of microphones that may be active simultaneously. FIFO: In this conference mode, only one microphone can be active at a time without intervention of the conference operator. Activation of another microphone switches off the current active microphone. Enables two microphones to be active at the same time. Other participants can switch their microphone in request mode; the first applicant who requested the floor gets the floor when one of the currently active microphones is turned off or when the chairman or conference operator grants the participant the permission to talk. Group 3: Works the same way as Group 1 and Group 2, with the alteration that three participants can have the floor at the same time. The only exception here is that the chairman microphone can always be activated.. Group 4: Works exactly like Group 1 and Group 2, with the alteration that four participants can have the floor at the same time. Override: Televic Conference Systems Works like the FIFO mode; however multiple microphones can be active at the same time. The number of microphones that can be active simultaneously is set by "Maximum Number of active Microphones" setting. 2013-06-28 70 Last mic on When this option is set , the audio of the last microphone which was switched off, still captures the sound , this way acting as an ambient microphone. In this situation the mic ringled and mic leds are not on anymore .When any other microphone is switched on again , the “ambient” microphone is then switched off. Limiter gain: select the gain limiter setting of the microphones: 0 = max setting , i.e. results in highest sensitivity of the microphone This last mic on option is only possible in stand alone mode -18 = min setting , i.e. results in lowest sensitivity of the microphones and no audio compression Note: The setting Maximum Number of Active Microphones has priority over the group setting , so regardless the chosen group setting , the number of participants that can have the floor at the same time is always limited by the Maximum Number of Active Microphones setting. Note: Set this on “-18” in case an external PA system with compressor limiter is used ! Note: If the Confidea wireless system is connected to a Televic conference system central unit, the conference mode settings will be managed from that central unit. Autogain reduction : reduces the gain per microphone in relation to the # of active microphones 0 = no gainreduction .. .. 9 = max gainreduction Reference: When using Confidea wireless in conjunction with other Televic conference systems and PC control software, please refer to the User Manual of those systems for more information on the use and setting of the various conference modes. Volume: Defines the loudspeaker volume. Televic Conference Systems 2013-06-28 71 VOX Vox Time out Confidea 2.0 contains also VOX functionality : microphones are switched on by voice detection Determines the time in sec the microphone stays on after no more sound is detected VOX time out setting which is to high might result in other microphones not being switched on because max amount of allowed microphones is reached and previous used microphones are not released. Vox time out setting which is to low might result in interrupted audio when there is a pause or low passage in the audio. VOX can only be combined with Override and Direct access mode VOX – direct access results in a more stable switch on/off behaviour . Certainly in combination with a short time out setting , FIFO-Override will result in a more “nervous” switch on/off behavior When longer time out settings are used , Vox – Override can be a better choice then Vox-Direct access because this way it is avoided that the next microphone can not yet be switched on because the time out of another one has not yet passed. Vox Treshold Vox Pencil drop suppression Avoids accidental microphone activation because of short sounds. This setting may cause a short mic activation delay General remark on use of VOX : A high limiter gain setting combined with strong audio input may result in the perception that the VOX activation is to slow due to the limiter release time. Interpreter Configuration determines the sound level needed to activate the mic by VOX VOX treshold is to be chosen in such way that a microphone is switched on directly after the person begins to speak. Defines the number of broadcasted interpretation channels. A (default) maximum of 16 interpreter channels can be set. A threshold setting whichs to high might result in a microphone not being switched on or switched on to late A threshold setting which is to low might results in a microphone being switched on by ambient sound Note: Choosing a high number of interpretation channels will limit the number of maximum microphone channels. Remark : also the limiter gain setting will influence the choice of the Treshold level . Televic Conference Systems 2013-06-28 72 Note: Note: Although it is possible to select the highest setting of number of active microphones together with the highest number of interpretation channels, it is advised to use the settings that are not marked in red! The ATM mode limits the max amount of translationchannels to 4 ! Note: Using settings marked in red may influence audio quality and max. reach In environments were interference from wifi signals Is an issue , ATM mode in combination with a manual fixed frequency setting in the RLAN LOW or ISM 5gHz band is recommended to limit the risk of disturbed audio due to RF interference ! (see also chapter 5.2.1 Operating Mode The selection between “stand alone” mode (without the use of a central unit) and Confidea wired or TCS5500 CPU can be made. 12.3.2. Unit Monitoring Robustness mode The Confidea wireless conference system 2.0 has a new feature which enables a choice between 2 RF Robustness modes :. Figure 12: Unit monitoring List STM Init State is the same transmission mode as is used in the Confidea wireless conference system 1.0 Units Initialized: Displays the number of initialized units currently linked to the system. ATM mode Units in Init List: Displays the total number of initialized units in the list. This transmission mode is specifically intended to be used in very challenging environments where a high density of wifi signals is present , which may cause RF interferences when STM mode is used.. Unit List In this section a unit summary is displayed. Televic Conference Systems 2013-06-28 Microphone Number: Displays the microphone number. 73 Serial Number: Displays the unit serial number. Status: Displays the unit status. Units can either be ‘Connected ‘or ‘Disconnected’. Init Init Control: Manual: In manual mode, each units needs to be initialized manually, by pressing the microphone button, before it is added to the Init List. ‘Start Init’: Pressing this control will start an initialization cycle. The green and red Microphone Status LEDs wil blink until the delegate unit has been recognized as ready to log on, by the Confidea Access Point. Once recognized , only the red Microphone Status LEDs will blink . Now the units are ready to initialize. Pressing the microphone button of each unit that needs to log on to the system , will register that unit within the Access Point. ‘Save and Stop Init’: This will stop the initialization and save the init list to memory. To add more units, restart the init cycle. ‘Clear Init List: This will clear the init list and allow you to start from scratch to build an init list. To add delegate units to an existing initialization, just start init without clearing Init list. Battery status: Displays the remaining battery capacity. The value indicates how many hours the unit can still be used before the rechargeable battery is depleted. Open Access: When the system is set to ‘Open Access’ any delegate or chairman unit that powers up within the range of a Confidea Access Point will log itself on to that access point, and its ID will be added to the Init List Link Quality: Displays an indication of the quality of the radio link the unit and the Confidea access point. The quality is expressed as Excellent, Good, Fair and Low. Version Displays the SW version of the delegate units Note: During the first minutes a unit is switched on, the battery status is not accurate and higher values can be displayed. This is caused by an averaging process and notby the behavior of the batteries. 12.3.3.

Update SW See chapter 11.4 Televic Conference Systems 2013-06-28 75 12.5. Encryption 12.5.1. Key Assignment Introduction To ensure a highly secured wireless system, the Confidea wireless system uses an encryption algorithm and mechanism that is fixed and cannot be changed. ‘Upload’ key: Pressing this button will upload the custom key to all units, currently logged on to the system. Units can only obtain the customer specific key during initialization. As soon as the initialization has been closed it will not be possible to access the system with other units. 13. Initialization The information that is transmitted over the radio link is encrypted with a key to make it inaccessible rd for 3 party equipment. This key is default and identical for all Televic units. 13.1. Introduction Security can be increased by adding a custom key, that is specific to a certain set-up or installation. Only the units and access point that share the same encryption key are able to communicate with each other. In this way, the system has become customer exclusive and as a result an even higher degree of security has been reached. One default key and 15 custom keys can be used. In stand-alone mode it is not required to initialize the units. However, if you want to authorize the wireless units that will be connected into the system you can follow the unit initialization procedure. (see also chapter 14 Encryption) Encryption Key In coupled mode, the same initialization procedures have to be followed as defined in the documentation from the central unit. To personalize the system and to further extend the confidentiality of your wireless conference system a unique encryption key can be defined. Default Key: When selecting this key, information over the wireless link is encrypted, using the Televic default key, used by all Televic equipment Custom Key: To further increase security, or to limit the access to the Access Point only to a well controlled number of delegate units, a custom key can be generated and sent to those units that are allowed to join. The result of this action is that only the units that know this key can access the system and participate in the conference ‘Calc.l’ key: Pressing this button will randomly generate a 128 bit key. The key appears in the window and can still be edited by the user. Televic Conference Systems The system can be controlled by the WCAP in standalone mode or together with the Confidea wired / TCS5500 Central unit in coupled mode. 2013-06-28 76 To select ‘Open Access’ click the radio button next to ‘Open Access’ on the ‘Init Units’ page (refer to Figure 13.3) 13.2. Stand-alone mode 13.2.1. Access modes Figure 13.3: Init units page - Open access When you use the Confidea wireless system in standalone mode, i.e. with no connection to a Confidea wired or TCS5500 central unit, the WCAP is responsible for the unit initialization and access control. In stand-alone mode, the WCAP supports two kinds of access: open access and controlled access. Open access: This is the default mode. Any unit can connect to the WCAP without authorization procedure Select this mode if the wireless units are not required to be authorized, before they are allowed to connect with the WCAP. This mode is especially useful for a fast setup. Controlled access: a unit can only connect after going through an initialization and authorization procedure. Note: Avoid using Open Access in areas with more than one active Confidea wireless system, as there is no control over which WCAP the delegate units will connect to. 13.2.2. Selecting the Access Mode To select the desired access mode go to the “Init Units” sub tab in the “Conference Management” menu from the web server (refer to Figure 13.1) Figure 13.1: Web server init page selection To select ‘Controlled Access’ click the radio button next to ‘Manual’ on the ‘Init Units’ page (refer to Figure 13.4) To control which wireless units connect with the WCAP a manual initialization of the units is required. Figure 13.4: Init units page - Manual The following screen will appear: Figure 13.2: Unit init page Televic Conference Systems 2013-06-28 77 Only the units that have been initialized and listed in the Init List will now be able to join the conference. 13.2.3. Unit initialization in ‘Open Access’ mode The init list is stored in the WCAP and stays in memory even after switching the WCAP off. Switch on all wireless units and wait a few seconds until the units have discovered the WCAP (see chapter 10) Next time the WCAP and delegate units are switched on, only these units that are in the Init List will be allowed to connect to the WCAP. All active wireless units will automatically connect with the WCAP and join the conference. 13.2.5. Adding a new unit in ‘Open Access’ mode 13.2.4. Unit initialization in ‘Controlled Access’ mode In ‘Open access’ mode, adding a unit requires simply to switch the unit on. In this mode, a manual initialization is required. The manual initialization procedure requires the use of the 3 buttons on the web server displayed above: “Start Init”, “Save and Stop Init” and “Clear Init List”. It will then automatically connect to the WCAP in operation. Take the following steps to initialize all units: Note: 1. Switch on all wireless units and wait a few seconds until the units have discovered the WCAP 2. Select the “Clear Init List”, , to clear any previously created initialization list. 3. Start the new initialization by selecting the “Start When multiple WCAPs with ‘Open Access’ are in operation in the same area, there is no control over which WCAP the new unit will connect to.

To add a unit to the initialization list, press the microphone button of the unit to add. 5. The LEDs will go out indicating that the unit has been added to the list. 6. Repeat step 3 for each unit that needs to be added. 7. When finished, stop and save the initialization by pressing the “Save and Stop Init” button, . Televic Conference Systems 2013-06-28 78 13.2.6. Adding a new unit in ‘Controlled Access’ mode 13.2.7. Reviewing Init information In a ‘Controlled Access’ set-up, adding a unit requires the following steps: 1. Switch on the wireless unit to add and wait a few seconds until the unit has discovered the WCAP 2. Open the existing initialization by selecting the “Start Init”, 3. 4. At any time it is possible to see how many units are known by the system, “Units in Init List”, and to see which units are actually connected with the WCAP, “Units Initialized”. This information is visible in the “Unit Monitoring” and “Init Units” sub tabs in the “Conference Management” menu (see Figure 13.2) , button. After you started the new initialization, the red Microphone status LED’s on the wireless unit(s) will start to blink. The LED’s on the units that are already known in the init list will automatically go out. Add the new wireless unit(s) by pressing the microphone button on the unit(s). Figure 13.5 shows the information on the screen when 1 unit is listed in the Init List but not connected with the WCAP: Figure 13.5: Init example 1 Figure 13.6 shows the information on the screen when 1 unit is listed in the Init List and this unit is switched on and connected with the WCAP: Figure 13.6: Init example 2 5.

Coupled mode If the WCAP is used in combination with a wired central conference unit, e.g. Confidea wired or TCS5500, then the initialization procedure explained for that wired unit has to be followed. Note: The Init control like displayed in the web server has no functionality when the WCAP is coupled with another wired conference unit. Reference: Refer to the manual of the connected central unit for the initialization procedure Televic Conference Systems 2013-06-28 80 14.3. Setting the default encryption 14. Using Encryption 14.1. Introduction To secure all communication between the WCAP and the wireless delegate units, all information that is passed over the radio link is encrypted by default, using a default encryption key. This key is identical for all Confidea wireless equipment. To this default key, a custom encryption key can be added. This further enhances the confidentiality, but can also be used to control access in an environment where multiple adjacent rooms are using a Confidea wireless conference system. In this way, access can be restricted to a single room or a selection of rooms. The custom key as it were adds a unique relationship between a wireless unit and a given access point. The default encryption mechanism can be set by following these steps: 1. Select the “Key assignment” sub tab in the “Encryption” menu from the web server. Figure 14.1: Web server key assignment page selection The following screen will appear: Figure 14.2: Key assignment page 14.2. Default encryption By default the system uses an encryption mechanism that is known by each unit in the wireless conference configuration. By using this setting it is possible to add new units in the conference configuration or using the delegate units with other WCAP’s at any time Note: The advanced encryption mechanism used in the Confidea wireless system makes decryption by third party equipment practically impossible. Televic Conference Systems 2. Select the “Use default key” option to return to the default encryption mechanism Figure 14.3: Default key selection 2013-06-28 81 Step 1 - Check your configuration 14.4. Custom encryption Before uploading the custom key check if all units in your system are switched on and connected to the WCAP. Verify if the correct number of units is loggedon by checking the “Units Initialized” number which can be found under the “Unit monitoring” or “Init Units” sub tabs in the “Conference management” menu. Please refer to the initialization chapter (ref.) for more information. The Confidea wireless conference system can be personalized by defining and selecting a unique encryption key. Note: The basis of the encryption mechanism cannot be altered, so adding a custom key does not affect the encryption strength. Default- and custom encryption yield an encryption strength that is equally high. Note: If delegate units have received custom keys in the past, it may be necessary to select the default encryption mechanism first, (refer to chapter 14.3 Setting the default encryption) to allow each unit in the system to access the WCAP. By using a customized key, only the units that have this key, i.e. on which the specific key has been uploaded, can connect with the WCAP. All other units will be rejected. It is impossible to receive the transmitted audio signal with a unit that does not have the customized key. Up to 15 customized encryption keys can be defined. Step 2 – Go to the Key assignment web page Select the “Key assignment” sub tab in the “Encryption” menu from the web server (refer to Figure 14.1.) Note: The key assignment page will appear (refer to Figure 14.2) Once uploaded to the delegate units, custom keys cannot be retrieved from the system. Step 3 – Enter a new encryption key In this example we will modify custom key 1. To manually enter a new custom key, choose a 32character long encryption key and manually enter it in the text box next to the “custom key 1” mark (refer to Figure 14.4). 14.5. Setting a customized encryption To set up your system with a custom encryption key, carefully follow these steps: Televic Conference Systems 2013-06-28 82 Caution: Caution: Only use hexadecimal characters i.e. choose 32 characters from the following list: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f. Only the units that are connected with the WCAP can receive the newly generated encryption key. Other units will be ignored! If a key shorter than 32 characters has been entered, then the remaining positions will be filled with zeros. Step 5 – Activating the new encryption key If a key longer than 32 characters has been entered, then the key will be truncated after the first 32 characters. The WCAP will start encrypting the transmitted data and audio after a custom key has been selected. Figure 14.5: Custom key selection Alternatively, the system can generate a random 128-bit (32 hex characters) encryption key for you. To do this, click the “Calculate 128-bit full key” button (refer to Figure 14.4). Caution: Figure 14.4: Custom key entry field Wireless units not containing the same encryption key as selected, because they were not connected with the WCAP at the time of upload, can no longer connect with the same WCAP. Step 4 – Upload a new encryption key The units will be ignored by the system! After a key has been generated it must be uploaded into the system. Not only the WCAP, but also all wireless delegate units that need to connect with the WCAP must know the same key. If the WCAP needs to use the selected key next time it powers up, push the button. Upload the key by clicking the “Upload key” (refer to Figure 14.4) Note: During the upload, the microphone LEDs will flash. Once the upload is successful, the LEDs go out. Televic Conference Systems 2013-06-28 83 14.6. Adding a unit with a customized encryption 14.7. Using multiple customized keys Follow the next steps to add a new unit in a Confidea wireless system that is configured to use a customized encryption key. It is possible to assign up to 15 different encryption keys. You can update all your units with the customized keys or just a subset. This way you can select the units that can join the conference by selecting the appropriate encryption key. Step 1 – Select the Default encryption key Please refer to the Setting the default encryption (ref.) for more information. Step 2 – Initialize the new unit Add the new unit to the initialization list. This step is only required if the access point is configured to work in manual initialization mode. Otherwise the unit will be automatically initialized. Please refer to the initialization chapter (ref.) for more information. Step 3 – Apply the customized encryption key to the initialized units After the new unit is initialized the customized encryption key can be assigned to the newly added units. Therefore follow the steps described in the Setting a customized encryption section (ref.). Televic Conference Systems 2013-06-28 84 15. Auxiliary in/out 15.2.2. External Processing 15.1. Introduction Activating the “external processing” option allows to add external signal processing equipment or a mixing board. On Confidea Access Point Plus (WCAP+) , auxiliary balanced analog input and output are available. So for basic systems , no additional central equipment is needed to connect the system to an external public address system or to add an external signal to the conference system. Additionally it is possible to connect the access point to a video conferencing system using the distance conferencing setting 15.3. Selecting auxiliary input/output settings When a WCAP+ is used , “conference management” menu contains an additional “auxiliary” sub tab as shown below. The distance conferencing and external processing options are only available in stand alone mode , and are disabled in coupled mode . In coupled mode , distance conferencing and external processing remain possible via Confidea wired or TCS5500. Fig 15.1 : Aux balanced input – output 15.2. Use of Auxiliary input output For both auxiliary input and output , status can be set to on or off and volume can be adjusted. When WCAP+ is used in Stand Alone mode , there are also “N-1” and “External processing” options available . 15.2.1. Distance conferencing Distance conferencing (= N-1) option adds external signal , via aux in , to the local floor signal and sends the local floor signal , via aux out , to the remote party.

(See section 3 system configuration) 16. Stand alone system 16.1. Basic discussion In a basic setup where only discussion is applicable, the Wireless Conference Access Point WCAP (see link to chapter WCAP) acts as a central control unit. This means the system can operate without the need of an extra central control unit (Confidea wired or TCS5500). Units applicable to this setup are listed below: Confidea DD Confidea CD Note: In this case the chairman needs to guide the meeting by using his prior and nextbutton. Microphone activation by an operator is not possible via web server application. In a standalone configuration power needs to be supplied to the WCAP separately. (see chapter WCAP power supply) Figure 16.1: Stand alone set up for basic discussion Televic Conference Systems 2013-06-28 89 Configuration and monitoring of the system can be done via the build-in web server, which is accessible via a standard web browser. (See section 4 system configuration) 16.2. Basic voting and opinion polling In a setup where there is only a need for basic voting or opinion check, the Wireless Conference Access Point WCAP (see link to chapter WCAP) acts as a central control unit. This means the system can operate without the need of an extra central control unit (Confidea wired or TCS5500). Units applicable to this setup are listed below: Confidea DV (Figure 6.1 and Figure 6.) Confidea CV Note: In this case the chairman needs to guide the meeting by using his prior and nextinline button. Microphone activation by an operator is not possible via web server application. In a standalone configuration power needs to be supplied to the WCAP separately. (see chapter WCAP power supply) Figure 16.2: Stand alone set up for opinion polling Televic Conference Systems 2013-06-28 90 Chairman has control over the voting session. With the voting session control buttons (see Confidea Wireless units - Controls and indicators) he can start, pause or stop a voting session. Figure 16.3: Voting control buttons After pressing the stop button, the voting session is terminated and the results are distributed to the information display of all registered Confidea WDUs. Figure 16.4: Voting information display Pressing the stop button a second time clears the voting results. Note: The voting results are not stored in a file in this setup. In case there is a need see use case CE2500 or CPU5500 Televic Conference Systems 2013-06-28 91 Connecting the Confidea access point to the central control equipment of the TCS5500 requires an additional splitter unit (SPL5525); Confidea Access Point is then connected to one of the “P…” ports of the splitter. 17. Connected to TCS2500, Confidea wired or TCS5500 As the Confidea wireless system is an addition to the Televic product family it is also possible to combine the Confidea wireless system with the existing /Confidea wired and TCS5500 system (refer to Figure 17.3: Televic Family concept) This family approach makes it possible to create a conference system fitting every customer needs. In situations where every now and then an extension of the fixed conference system is required, adding some wireless units can reduce the setup costs drastically. Depending on the demands of a project the central control equipment of the TCS2500 , Confidea wired or TCS5500 does the job. The Confidea access point (WCAP) can be directly connected to one of the digital output busses of the TCS2500 central control unit or Confidea wired Figure 17.1WCAP connected to TCS5500 In the following section three possible applications are described. This will help to define the correct system architecture for a given project. Reference: When using Confidea wireless in conjunction with other Televic conference systems and PC control software, please refer to the User Manual of those systems for more information.

Discussion For these applications, delegates of the meeting have a contribution unit with only a microphone to participate in an ongoing discussion. Several criteria can influence the choice of the Televic central control unit to be used. The criteria described below should guide you in designing the best possible system architecture for a given project. Figure 17.4: Central control equipment selection criteria Table 17.1: Project size vs. Televic system Project size The number of participant units in a meeting will influence the decision on the system to use. Number of Participants TCS2500 or TCS5500 Confidea wired The TCS2500 and Confidea wired central control unit is limited up to 120 active wired delegate units. Projects requiring a larger number of participants should use the TCS5500 central control unit with expandable system architecture. max 120 wired + wireless > 120 wired + wireless • • • Table 17.1 below gives an overview on the system compatibility. Televic Conference Systems 2013-06-28 94 External Audio Peripherals Expandable Expandable PA systems: Whereas the Confidea WDUs have a build in loudspeaker, some meeting rooms are equipped with external PA systems with loudspeakers installed on walls or in ceilings. Making use of such a setup, the floor language of the conference system needs to insert into the PA system. This requires an analog output, which is available on the central control equipment of TCS2500 , Confidea wired and TCS5500. Recording: Whenever meeting reports need to be written or audio of meetings is being published on the web, recording needs to take place during the meeting. The recording device (hardware or software solution) needs to have an analog input signal provided by the conference system. The Televic TCS2500 , Confidea CU and the TCS5500 central control units have 6 analog outputs available. Additional outputs can be provided by adding external TCS5500 output equipment to the TCS5500 system. Audio reproduction: Feeding external audio signals (music before meeting, DVD sound, input external microphone, telephone line, …) into the conference system requires analog inputs on the central control unit. The TCS2500 , Confidea wired and TCS5500 central control units have two analog inputs. If this is not sufficient the TCS5500 system has the capability to connect additional input equipment.

Advanced Voting Operator Control: Systems requiring a great degree of control can be equipped with the Televic software suite. This application makes it possible, depending on the license, to control the microphones in a meeting, assign delegate names, control speech time, display delegate and speech time information on monitors or projection screens. It offers easy initialization and configuration capabilities supporting an easy set-up and breakdown, essential for successive meeting planning with low delays like convention centers. Furthermore it visualizes the battery and RF quality status of all units, giving the operator/technician the ability to assure no interruptions once the meeting started. Camera Control The stand alone voting setup can be seen as an informal voting session. Making use of a Televic voting software suite enables following features: Voting agenda Voting session configuration options Voting result reporting Voting logging Voting result visualization All of these options are available for as well TCS2500/Confidea wired as TCS5500 systems. Main differences between the two systems are: Voting by authority Customizable voting result visualization Table 17.4: Voting vs. Televic system To enable a camera system to visualize the currently active Confidea user, a device bus controller needs to translate the commands received from the Televic system into preset positions of the camera control system. The TCS2500 , Confidea wired and TCS5500 systems will do the job. Voting Authority Result visualization TCS2500/Confidea wired TCS5500 • fixed customizable The difference between the TCS2500/Confidea wired and the TCS5500 system on connectivity level is the way the communication takes place. The TCS2500/Confidea wired uses a serial communication protocol, whereas the TCS5500 system has additional IP connectivity.

Interpretation Systems with simultaneous interpretation as a requirement always require a central control unit in combination with the interpreter desks. Installation Next to these points it is also possible to connect interpreter systems of other vendors. That way it is possible to use the Confidea wireless system without the need to change all the interpreter desks. The PIO unit of the TCS5500 plays an imported role in such configuration handling the floor and interpretation languages between the two systems. Whereas the TCS2500 interpreter desks are of the table-top type, the TCS 5500 interpreter equipment can be semi-flush mounted. Conformity Standard The ID5500 interpreter desk is conform to the ISO 2603 standard and approved by interpreter organizations as the European Commission (SCIC), United Nation, AIIC. Interpretation capabilities The Confidea wireless system has the standard capability to send up to 16 languages to the contribution units. TCS2500 , Confidea wired and TCS5500 systems are capable of handling that number of languages. External Equipment As already described in External Audio Peripherals the number of analog outputs required for recording or needed to connect to an Infra red distribution system will determine the central equipment to be used.
